How long do I have to pass all four sections of the examination?

Once you pass a section(s) of the examination, you are allowed a maximum of 18 months to pass all remaining sections in order to retain credit on the passed section(s). If you do not pass all four sections within that 18-month period, you will lose credit for the first section of the exam you passed. A new 18-month period will commence with a start date of the second section that was passed.
